How to fix Undefined Index warnings?

Question

This is the warning I am getting.

Undefined index: errormsg in /var/www/html/ies.aacrao.org/apply/begin.php on line 8

on this line of code:

if ($_GET['errormsg'] == "no_appid") {

$_SESSION['errormsg'] = "There was a problem with your application.  Please reenter all data.";

}

Hope someone can help me put.

It means $_GET['errormsg'] wasn't set. You could check for that like this:

if (isset($_GET['errormsg']) && $_GET['errormsg'] == "no_appid") {
}

You could check with isset like

if (isset($_GET['errormsg']) && $_GET['errormsg'] == 'no_appid') {
    $_SESSION['errormsg'] = "There was a problem with your application.  Please reenter all data.";
}

look at php isset
